18Gbps transfer rate earns Supercomputing Bandwidth Challenge crown

Team led by Indiana University nearly doubles peak transfer rate of nearest competitors

A team led by Indiana University won this year's Supercomputing Bandwidth Challenge by achieving a peak transfer rate of over 18Gbps out of a possible maximum of 20Gbps.

The goal of the competition was to devise a way to fully utilize one 10Gbps path end-to-end from the Supercomputing 2007 convention in Reno back to the competitors' home academic institutions. This goal is important, say Bandwidth Challenge sponsors SC07, because very few high-bandwidth networks fully utilize their potential speeds.

The IU team created its winning entry using the IU Data Capacitor, a system that the team says is used to store and manipulate massive data sets to achieve a sustained data transfer rate of 16.2Gbps. At its peak, the system nearly doubled the peak transfer rate of its nearest competitors, clocking in at 18.21Gbps. The project utilized an international network path that ran through a variety of research networks, including Internet 2, the pan-European GEANT and Germany's DFN.

To demonstrate its network's high speeds, the IU team ran several different computer applications that required large amounts of bandwidth, including the live acquisition of X-ray crystallography data, the electronic preservation of ancient Sanskrit manuscripts and simulations of high-energy physics reactions.

"This project simultaneously pushed the limits of networking and storage technology while demonstrating a reproducible model for remote data management," says Stephen Simms, IU's Bandwidth Challenge project leader. "Best of all, we did this using a variety of research applications that we support every day at Indiana University."

IU's Bandwidth Challenge Team included partners from the Technische Universitaet Dresden, the Rochester Institute of Technology, Oak Ridge National Laboratory and the Pittsburgh Supercomputing Center.

Last year's Bandwidth Challenge was won by a team from the University of Chicago, which achieved sustained transfer rates of 8Gbps and a peak transfer rate of 9.18Gbps.

I would recommend this device for families and small businesses who want one safe place to store all their important digital content and a way to easily share it with friends, family, business partners, or customers.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
